Compile with debugging on, run 'nm --size-sort ./busybox'
and then start with the biggest things and make them smaller...
-
-----------------------
-
busybox.defs.h is too big and hard to follow.
Perhaps I need to add a better build system (like the Linux kernel?)
-----------------------
-
Feature request:
/bin/busybox --install -s which makes all links to commands that it
can support (an optionnal -s should be used for symbolic links instead
of hard links).
